VOCABULARY Land Bridge Theory Migrate Ice Age Glacier
WHAT IS THE LAND BRIDGE THEORY? According to the Land Bridge Theory, Native Americans migrated from Asia to North America during the Ice Age. Very cold temperatures caused large areas on Earth to freeze and form glaciers. These glaciers caused the level of the water in the ocean to drop. The land that once was under water became exposed creating a long land bridge that connected North America to Asia.
WHERE WAS THE LAND BRIDGE FORMED? The land bridge was formed between Asia and North America. This narrow body of water that now separates Asia and North America is called the Bering Strait. Watch an animation of the Land Bridge Theory here. ng i r Be ait Str
